IMPROVEMENT IN CORN-VPLANTIERS.

Specification forming part of Letters Patent No. 32,294, dated May 14, 1861.

To all whom it may coozcern:

Be it known that I, H. J Heart), of Onarga,

in the county of Iroquois and State of Illinois, have inventedla new-and Improved Oorn- Planter; and do hereby declare that the following is a full, clea.r, and exact description of f the same, reference being had to. the ann exed drawings, making a part of this specification,

in which- Figure 1 is a side sectional view of my invention, taken in the linear to, Fig. 3; Fig. 2, a transverse vertical section of the same, taken in the line a" m, Fig. 3; Fig. 3, a plan or top view of the same.

Similar letters.of reference indicate corre sponding parts in the several figures.

V This invention relates, first, to a novel and improved means for operating the seed-distributing device, whereby the latter may be actuated by the driver when planting in check- 'rows is required, or actuated automatically from one of the ground-wheels when it is designed to plant in rows for cultivation in one direction only.

The invention relates, secondly, to an improved means for elevating the front part of the machine, so that the fnrrowshares or run- I 11ers may be free from the earth, and the machine readily turncd, when required.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it,

A represents a rectangular frame, the front part of which isIsupported by two runners, B B, one being at each side of the frame. The back part of the frame is supported by two wheels, 0 C, which are in line with the rum hers B B. D is the drivers seat, placed on the back part of the frame A.

At each side of the frame A, on its upper part, there is placed a seed-box, E,,'said seedboxes being directlyoyer the back part of the runners B B. From the bottom of each seedbox E a spout, F, extends down to the back end of the runner B below, as shown in Fig.1.

G is a shaft,which isplaced transversely on the frame A, and has a cylinder, a, on each end, said cylinders being at the bottoms of the seed boxes E E, and each provided with a seedcell, 11. a On the periphery of each cylinder at a cut-'ofl' brush, 0, bears.

On the shaft G, at its center, there is placed a pinion, (I, which gears into a segment-rack,

H, which has its center at e. To the back part or the segment H, just above its center, there is attached a levemf, the use of which will be presently shown, and on the upper arm,

g, of the segment there is placed a sliding weight, h, which may be secured at any desired point on the arm 9 by a set-screw, t. (See Fig. 1.) The segment-rack His connected by a stirrup, I, to a lever, J, which has its fulcrum at'j. The back end of this lever extends underneath a tappet, K,which is placed loosely on the axle L of the wheels 0 C, and is made to turn with the axle, when necessary, by means of a sliding clutch, M, which is placed on the axle and is 'moved by a lever, N, and made to engagewith one end of the hub of the tappet. This will be fully understood by referring to Fig. 2. A spiral spring, 0, on the axle L has a tendency to keep the clutch Mengaged with the tappet K.

of rotation of a pin, a, which projects from the side of the tappet and prevents the casual movement of the latter.

The operation of the above-described parts is as follows: As the machine is drawn along the runners B B form the furrows, and the clutch M, when engaged with the tappet K,

causes the latter to rotate with the axle L, The tappet acts on the, back end of the lever J,raising the front end ofthe latter, and con sequentlythesegment-rackH,which rotates the pinion d and the shaft G, and causes the seed cells I) of the cylinders a a on shaft G to pass within the hopper and fill with the seed, and

as the prominences of the tappet pass the end of leverJ the weight It causes the segment-rack to descend and the seed-cells b to turn out I The velocity of the backward movement of v the shaft G may be'regulated by adjusting the gaged from the tappet, and the segment-rack a greater or less momentum,jar, or concussion,

' A A, between which a bent lever, B, which weight h nearer to or farther from the frontend of its arm 9, and in case the corn is to be planted incheck-rows the clutch M is disen,

H is operated by the driver. By varying the velocity of the backward movement of the shaft G by'means of the adjustable weight h,

as may be required, may be given the seed at the termination of the backward movement of the shaft to insure the discharge of the seed. 0n the front part of the frame A, at its center, there are secured two semicircular racks,

is attached to the back end of the draft-pole 0, works, the lever B having its fulcrum at a on the frame. The lower end of the bent lever B isconnected by a link, D, to the back end of the draft-pole, as shown clearly in Fig. 1, and to the upper end of the lever B a slidestop or pawl, a, is attached, by operating which the lever B may be secured at any desired point of its movement. It will be seen, therefore, that by'drawing the upper end of runners B B raised above the ground, so that the machine may be readily turned when re quired. The stop or pawl a, retains the lever B, and consequently holds the front the machine in an elevated state.

I do not claim the runners B B, for they have been previously used but I do claim as new and desire to secure by Letters Patent- 1. The arrangement of the tappetK on axle L, the lever J, segment-rack H, with sliding weight h, and pinion d on shaft G, substantially as and for the purpose set forth.

2. The arrangement of the bentlever B, attached to the frame A and draft-pole O, the semicircular racks A, and pawl or stops at, as and for the purpose herein set forth.
